Hey, I'm working in maya, and I'm pretty much wondering if there is a function for edge loops/verticies that does the same thing as relax UV's? I have a few edge loops on my model that are a bit wonky, and while I can go in and rework them all that takes a lot of time for something that should be a relatively simple…
Select your edge loop than convert it to vertices with Edit Polygon>>Selection>>Convert selection to vertices. Then you can use the Polygons>>Average Vertices tool which has a similar effect as relax UV. Or with the vertices selected you can use the Edit Polygons>>Sculpt geometry tool set to Smooth.
